There are several hidden treasures among the volcanoes on the Big Island of Hawaii. The one that I found most fascinating was a short (0.7 mile) hike from the Chain of Craters road to the Pu'u Loa Petroglyphs.
I was most fascinated that this land has been lava coated—and recoated—for ages and yet these petroglyphs still managed to escape centuries of fresh molten lava.
I also thought this image, etched in the rock, was the likeness of a couple and imagined some ancient Hawaiian man carefully carving out the images and comically telling his wife: "I lava you a lot."
